6 laims. (Cl. 4-237) My invention relates to methods of making toilet seats and has particular reference to methods of making toilet seats, toilet covers and similar articles from corrugated paper.

This is a continuation-in-part of my application Serial No. 272,946, filed May 11, 1939, which matured into Patent No. 2,185,169. r

My invention has for its object to provide a method of making toilet seats and covers by winding a strip of a corrugated paper on a mandrel and cementing together the successive turns. I prefer to use for this purpose corrugated paper comprising a corrugated strip to one side of which a flat sheet of paper is glued, the strip being so cut that the corrugations extend straight across from one edge of the strip to the other. Such a strip is very flexible, so that it can be wound into a tight roll following the shape of the mandrel. The article thus obtained is very light in weight, a large portion of its volume representing air spaces between the corrugations.

At the same time it is very strong, resisting compression, since the corrugations extend directly across from one side of the article to the other, being highly resistant to compression. The successive turns may be glued together during the process of winding or they may be secured together upon completion of the winding by applying glue to the sides of the article, thereby gluing together the edges of the strip. The edges of the article can then be rounded off by grinding or other suitable mechanical process. The finally shaped article can be given smooth appearance by applying a layer of a suitable plastic compound, such as plastic wood, to the outer surface of the article, soas to fill the spaces between the corrugations at the surface, leaving air spaces inside the article. The surface of the article can then be polished smooth and painted with a suitable water-resisting paint or enamel. Articles made by my method are very light, inexpensive and possess relatively great rigidity. They are superior to ordinary seats made of wood in that they do not warp, do not crack, and retain their shape after long usage. They can be refinished and re-enameled from time to time.

The outer contour or shape of the article can be controlled by placing suitable inserts between the turns of the strip as described in my foregoing patent application. These inserts canbe also usedfor attaching hinges by suitable bolts or screws. Instead of polishing or painting the outer surface of the article, a moulded cover may be cemented on the outside, as also described in 4 my foregoing application.

Another modification of my method as described in my foregoing patent application. consists in winding a long cylindrical body on a suitable mandrel, using for this p se a wide sheet of corrugated paper with corrugations extending lengthwise of the mandrel. Inserts, if such are required, may be provided in the form of long strips or bars inserted between the turns at suitable points. The cylindrical body, upon completion of winding, is then cut by suitable gang cutters or saws intoa plurality of relatively thin boards which are then finished into toilet seats or seat covers.

My invention is more fully described in the accompanying specification and drawing in which:

Fig. 10 is a perspective view showing my method of making seats.

My improved method ofmaking toilet seats and similar articles consists in winding a strip of corrugatedpaper around a suitable mandrel I as shown in Fig. 10. The corrugated paper preferably consists of a corrugated strip 2 glued at one side to a flat. strip 3 so that it retains its longitudinal flexibility, being at the same time fully rigid in transverse direction, the corrugations being aligned transversely tothe strip. The successive turns of the corrugated paper strip are held together as by applying glue to the flat side of one turn and pressing against it the tops Figs. 1 and 2. with such inserts a flat rear side can be obtained for mounting hinges which support the seat on agtoilet bowl (not shown) Additional inserts B may be provided for bolts or screws I which fasten hinges 8 (Fig. 3) to the seat.- The inserts 6 are preferably placed when the seat is fully formed, by drilling a corresponding hole edgewise through the seat and cementing the insert in the hole. The inserts are pref! erably made of a macliinable material, such as wood, fiber, etc., or they can be made of pieces of corrugated board.

Another method of making toilet seats is shown in Fig. 4. The seat 9 is wound to a larger overall size as shown in dotted lines' ID. .The excess material is afterwards removed by trimming or grinding.

The'covers ll, Fig.5, are formed in a similar manner by winding a strip around an elongated mandrel or core ii. The core in this case is not removed upon completion of the winding, as is the case with the seat," but is left in the cover, being firmly cemented in its place. It is also possible to wind the cover without any core, using the first turns of the strip as the core.

The seat, when fully wound, is ground or trimmed around so as to round oil its corners as shown in Figs. 2 and 3. A smooth moulded by the straight corrugations extending across the thickness of the seat. The surfaces of the seat are ground and polished when the. plastic material becomes sufllciently hardened. A coat of paint or enamel can be then applied to the polished surface, if desired. I

Another method of finishing the seat is shown in Fig. 6. The seat, upon winding and before -.mounted band saw.

' of'the inventionaassetforth. in'the a'ppended the glue or plastic material is hardened, is

formed in a specialmould, so that its upper side is made convex as shown. The seat may be left in the mould until the plastic or cementitious material is hardened. Upon removal from the mould, the seat is ground fiat on the under side.

Another method is shown in Figs. 8 and 9. especially applicable to a mass production. A wide sheet l5 of corrugated board is wound on a long mandrel or core l1,.the latter being mounted on. a shaft ill for its rotation. Long inserts l9 are placed between the layers of the sheetto form corners of the seats. The completed article in the form of an elongated cylinder 20 is cut into a number of separate seats by means of circularssaws 2| mounted on a shaft 22.

For splitting the board or wound cylinder 22 agang saw can be used, either on a reciprocating frame or in the form of a continuous zig-zag It is understood that myinvention may be fur- .ther modified without departing from the spirit claims. I
